SPOOL.

Application filed January 4, 1924. Serial No. 684,310.

To all whom it may concern,

Be it known that I, Gnonou H. BIRD, a citizen of the United States, anda resident of Brooklyn, in the county of Kings and State of New York,have invented new and useful Improvements in Spools, of which thefollowing is a specification.

This invention relates more particularly to spools for receiving ribbonand other narrow fabrics as it is usual to prepare them for sale in drygoods stores and the like.

The objects of the invention are to secure an improved and simplifiedconstruction of such a spool, whereby the ribbon may be readily packagedfor the market and yet its winding and inspect-ion conveniently providedfor; to produce a spool consisting of a core or body portion on whichthe ribbon is first wound and inspected, and side flanges of sheetmaterial which can be merely pressed into place; to provide grooves atthe ends of the core or body portion for receiving said flanges; toprovide a spool of this character embodying novel and improved featuresof construction whereby the usual wooden core, cardboard body on whichthe ribbon is wound and the side flanges for holding the body on thecore can be easily and quickly assembled without gluing or similarlyfastening the core in the body, and to obtain other advantages andresults as ,may be brought out by the following description.

Referring to the accompanying drawings, in which like numerals ofreference indicate the same parts throughout the several views,

Figure 1 is an edge view of one form of my improved spool with ribbonwound thereon;

Figure 2 shows the core or body portion of the spool with its flangesremoved;

Figure 3 shows the ribbon wound on the core or body portion and oneflange in the act of being applied;

Figure 4c is a side view of the spool, as shown in Figure 1;

Figure 5 is a similar view of the core or body portion alone, as shownin Figure 2;

Figure 6 is an edge view of another form of spool;

Figure 7 is a composite edge view partly in section of the parts of thespool disassembled and in their relative positions;

Figure 8 is a side elevation partly in sec? tion of the spool shown inFigure 6;

Figure 9 is a transverse vertical sectional .view through the spool;

Figure 10 is an edge elevation of the core;

Figure 11 is an end elevation of said core, and

Figure 12 is an end elevation of the caps for securing the flange to thecore.

In the specific embodiment of the invention shown in Figures 1 to 5 ofsaid drawings, 1 indicates the core or body portion of my improvedspool, which is in general form cylindrical with a hole 2 through it formounting upon a mandrel or the like for winding and similar purposes.This core or body portion 1 may be made of any suitable substance, and Ihave found close grained wood such as thread spools are made of to bevery satisfactory. A middle portion of the length of the spool is leftcylindrical to receive ribbon of the desired width to be wound thereon,such ribbon being indicated by the reference numeral 3 in the drawings,and grooves 4c are cut into the periphery of the core or body portion 1at opposite ends of the ribbon-receiving surface 5, these grooves beingadapted to receive flanges 6 to lie against the opposite sides of thecoil of ribbon, as shown in the drawings, and protect the same. Theextremities 7 of the core or body portion 1, outside said grooves 4, 4:,are beveled, as shown at 8 in the drawings, to enable the said flanges6, 6 to be pressed over said extremities 7, and said flanges arepreferably made of such material that when a central hole 9 is formed inthem, smaller than the diameter of the extremity? of the core orbodyportion 1 but as large or larger than the diameter at the bottom of thegroove 4c, the edges of the flange around said hole 9 will spring overthe extremity 7 and snap into place in the groove t, as illustrated inFigure 3. In. said figure the edges 10 of the opening are shown beingdeflected to snap over the extremity 7 of the core or body portion andsnap into the groove l, and T have found that p'asteboard willatisfactorily act in this manner, although I do not wish to strictmyself to any particular material. When in place the flanges 6, 6 lieclose against the sides of the roll of ribbon 3 and protect the same aswell as keep it in proper shape.

In the specific embodiment of the invention shown in Figures 612 of thedrawings, 11 indicates a cylindrical core with a hole 12 through it formounting upon a mandrel for winding or similar purposes. This core 11receives axially a drum 13 which is shown hollow and made of pasteboardwith central openings 14 at its opposite sides 15 so that it can bepushed onto the core and fit without looseness thereon, its

opposite sides being substantially flush with the ends of the core 11.Flanges 16, 16 lie against said opposite sides 15 of the drum 13 andagainst the ends of the core 11 and project beyond the periphery of thedrum so as to receive between themselves the ribbon and protect it. Eachflange 16 has a central aperture 17 which somewhat larger than the hole12 in the core and yet smaller than the outside diameter of said core,and when the flange is disposed in central axial alinement with thecore, in manufacture, a cap 18 secures each flange 16 to the core. Thesecaps each having a rim 19 adapted to engage the outer side of the flange16 and a retaining por tion 20 which I have shown as cylindrical whichis adapted to pass through the central opening 17 of the flange and beembe' ded in the end of the core 11. Obviously when this is done theseveral parts of the spool are secured firmly together and yet. the saidflanges can be easily applied after the drum has been wound. I havefound it very satisfactory to make the flanges and drum of cardboard,the core of wood and the caps of light sheet metal, but it will beunderstood that any of said parts may be made of any suitable materialdesired. This form of spool is further advantageous in that such spoolsmay be easily and compactly stacked end to end, the caps 18 beingsubstantially flat so as not to materially project from the ends of thespool as do the ends of the core 1 shown in Figures 1-5 inclusive.

A drum such as the drum 13 also can be utilized with the spool shown inFigures 15 inclusive, and in both constructions the flanges 6 and 16 andtheir sep arable connection with the respective cores 1 and 11 enable asimple operation in assembling of the pants of the spools and withoutthe use of glue or the like for securing the cores in the drums. Oneflange 6 or 16 may be secured to one end of its corresponding core 1 or11, the drum carrying the ribbon slipped over the core and then theother flange secured to the other end of the core, so that the core" issecurely held in the spool and the drum on the core.

Obviously the spool described can be very readily and cheaply made, theribbon cav be quickly and easily wound thereon and securely held andamply protected by the spool. Various detail modifications could bemadein the manufacture of my inven tion, without departing from the spiritand scope of the invention, and I do not wish to be understood asrestricting myself except as required by the following claims whenconstrued in the light of the prior art.

, Having thus described the invention, what I claim is:

1. In a spool of the character described, the combination of a drum toreceive ribbon or the like and having an axial opening, a core to fitwithin said opening in the drum, a substantially flat flange applied toeach end of said core and engaging the corresponding end of said drum tohold ribbon thereon, and means for securing said flanges directly tosaid core, whereby the spool may be assembled by securing one ofsaidflanges to one end of said core, slipping the drum with the ribbonthereon endwise over said core or slipping the corei'into the opening insaid drum, and then securing the other of said flanges to the other endof said core.

2. Ina spool of the character described, the combination of a hollowdrum to receive ribbon or the like and having end walls with axialopenings, a core to fit within said openings in said drum, asubstantially flat flange applied to each end of said core and engagingthe corresponding end of said drum to hold ribbon thereon, and means forsecuring said flanges directly to said core, whereby the spool may beassembled by securing one of said flanges to one end of said core,slipping the drum with the ribbon thereon endwise over said core orslipping the core into the opening in said drum, and then securing theother of said flanges to the other end of said core.

3. In a spool of the character described,

the combination of a drum to receive ribbon or the like and having anaxial opening, a core to fit said opening with one of its endsprojecting from the corresponding end of said drum, said projecting endof the core having a peripheral recess, and a pair of flanges securedone to each end of said core, one of said flanges having an axialaperture to spring over the recessed end of said core and into saidrecess. 7

4. In a spool of the character described, the combination of a drum toreceive ribbon or the like and having an axial opening, a core to fitsaid opening with one of its ends projecting from the corresponding endof said drum, said projecting end of the core having a circumferentialgroove adjacent its extremity and its extremity rounded outwardly ofsaid groove, and a pair of flanges secured one to each end of said core,one of said flanges having an aperture with marginal portions to bedeflected by said end of the core as the flange is forced thereover andreturn to their initial position in said groove. I

5. In a spool of the character described,
